ok so remember
if x=degrees then the measure of the arc is
x/360=arclegnth/circumference
(if you understna that the angle's fraction out of 1 whole=arc's fraction out of circumference, you can use that info to make your own formula)
so
find circumference
c=pid
c=3.1416
c=50.24

so
270/360=x/50.24
3/4=x/50.24
multiply both sides by (450.24)
150.72=4x
divide both sides by 4
39.68
round
37.7

answer is D
